This is a more general question than just about Strategic Reliabilism. Obviously, many decisions occur in a social context in which the majority of other people do not necessarily, or even usually, behave based on rational strategies. Given that any strategy a rationalist chooses to use interacts with, or even depends on the irrational behavior of those other people, how can such irrationality be factored into a rationalist-based decision? Perhaps this question is a restatement of: Nothing is Foolproof!

Determine what you want other people to do
Use your best understanding of human behavior, both rational and irrational, to guess what circumstances will cause them to do that
Determine how you might be able to cause those circumstances
Weigh that against the other costs & benefits of those actions.
